Best for: Hot sleepers, silky-feel lovers, sustainable buyers
The coolest sheet set we've compared — 100% eucalyptus (Tencel), which wicks moisture faster than any cotton weave.
Worth it at $119$199 for eucalyptus lyocell, which does sleep cooler than cotton - but cooling is the only thing the premium buys, and a plain cotton set still scores 8.4.Buffy sheets are 100% eucalyptus (Tencel Lyocell) — the coolest natural fiber commercially available. Feels like silk without the fragility. Naturally moisture-wicking. Machine-washable. Comes in solid colors + prints. Priced level with Brooklinen Luxe at Queen, the choice is cooling eucalyptus versus cotton sateen hand-feel. If you sleep hot, this is the sheet upgrade that actually solves the problem.

Buffy wins by a lot. Eucalyptus sleeps cooler than cotton and much cooler than microfiber. If overheating is a real problem, Buffy solves it.
No — Tencel is actually more durable than cotton. Reviewers report 3+ years of use with no shape loss. The eucalyptus origin doesn't degrade quickly.
Both cooler than cotton. Tencel eucalyptus is slightly cooler and more durable. Bamboo is cheaper. If budget matters, bamboo. If pure cooling matters, Buffy.
Tencel has natural drape + softness — feels closer to silk than cotton or microfiber. Not slippery like satin. Machine-wash care preserves the finish.
